陕西省丹凤县石板沟地区铀矿特征及找矿方向探讨
|
摘要
石板沟地区大寺沟铀矿点位于陕西省丹凤县境内,与小花岔铀矿床位于同一构造线方向上。其铀成矿条件矿化类型与光石沟、小花岔等大中型伟晶花岗岩型铀矿床具有较强的可比性。通过对光石沟、小花岔典型矿床成矿要素的深入研究,并将该成矿要素系统引入本区,找矿方向明确,结合石板沟地区的地质、物化探特征,认为该区铀成矿条件有利,推测成矿前景较好。
The Dashigou uranium mine at Shibangou area is located in the territory of Danfeng county in Shanxi province,which is located in the same structural direction as the Xiaohuacha uranium deposit. It's uranium mineralization conditions and mineralization types are relatively comparable with those of large and medium-sized pegmatite type uranium deposits,such as Guangshigou and Xiaohuacha. Based on the deep study of the metallogenic factors of the typical deposits of Guangshigou and Xiaohuacha, then the metallogenic elements are systematically introduced into the region. Combined with geological, geophysical and geochemical characteristics, it is considered that uranium mineralization in this area is favorable and has a good prospect.
